Maple Leaf WONDER Hop Bucking for Marui /WE GBB & VSR ( 50° )

- Slightly narrow entrance for better sealing to achieve more consistent power output.- Special pressure point geometry greatly improves hop up performance and more predictable trajectory.

- C-Clip to Enhance Lip Stiffness for Further Sealing- Suitable for Marui / WE / KJ GBB Pistols, WE GBBRs and VSR-10 compatible Air Cocking Rifles

- No indexing tab for better compatibility with newer WE GBBs

NOTE: Due to special pressure point geometry, this product is optimized for use with inner barrels with open type hop up slot.( i.e. Marui original pistol inner barrel and most compatible inner barrels )
